Very Computer

Hi gurus,

I have an AIX system running AIX 4.1.5. To this system we have mounted
(via NFS) a remote file system residing on a Linux system. From the AIX
system we can see the files, we can also read/write/create them.

When I run a Microfocus Cobol program (on the AIX system) that wants to
use a file on the mounted Linux file system, the program hangs during
the OPEN of the file. On the AIX console a message like "rpc.statd
cannot talk to remote statd daemon" is issued in a loop.

What do I have to do to start "statd" and "lockd" on the Linux system?
Or is there a way to manage this from the AIX system?

Note:
The same program works ok using two AIX systems.
When I terminate statd to avoid the error messages and the blocking, the
OPEN in the program fails with "Too many locks".

Hi.

You only need to run statd, or at least you do when connecting Linux and
SunOS together.  Statd is just a status monitor, it interacts with lockd
on the local machine to provide crash and recovery functions for the
locking services on NFS.

It allows you to perform commands like:-

             rup mouseorgan

Which returns the uptime of the host known as mouseorgan.

There is a rpc.statd daemon for Linux, its on either sunsite or tsx-11, I
sorry I forget which.  If you prefer I got a version here which I could
email to you (uuencoded of course ;->)

AFAIK statd and lockd are not available for Linux, but there will be
a kernel based implementation in Linux 2.2 in half a year or so. If
you really need them now, checks out the FreeBSD sources. I think they
have "stub" servers that don't actually do anything but emulate statd
and lockd to make remote NFS clients happy.

Mike.
